GemRB is created by the GemRB team, see www.gemrb.org. GemRB (Game engine made with pre-Rendered Background) is a portable open-source implementation of Bioware's Infinity Engine. It was written to support pseudo-3D role playing games based on the Dungeons/Dragons ruleset (Baldur's Gate and Icewind Dale series, Planescape: Torment).
